The global automatic train control market size was valued USD 2.5 billion in 2020 to USD 3.9 billion by 2027, at a Compound Annual Growth Rate (CAGR) of 10.7% during the forecast period. Emerging trend of smart cities, population explosion and hyper urbanization, technological advancement, continuous research and development in the field of automation technology, development of semi-autonomous and autonomous trains are some key factors influencing the market growth. However, factors such as high deployment cost of ATC solutions and complexities in integrating ATC solutions with legacy systems are hampering the market growth. In addition, favorable government support provides huge growth opportunity for the market. Automatic train control Market integrates all systems and functions to ensure the train’s safe operation. They employ a variety of technologies, with three major systems in place: automatic train supervision, automatic train operation, and automatic train protection. The ATC’s major goal is to keep track of the train’s movement in order to ensure passenger safety and security. To drive the global market, high statistical development, higher-urbanization, mechanical headways for expanding traveller accommodation, and a rising pattern of brilliant urban communities are required. The mainline component is expected to be a significant supporter of the Automatic Train Control (ATC) showcase development within the forecast time range, based on train type. Passenger and freight trains are both part of the mainline train system. The majority of mainline trains follow extensive routes that pass through nearly every intersection in the country. These trains are, in a sense, designed for lengthy journeys. Mainline trains are gradually being restructured to include trend-setting features.
